Overview
The Boante BAT53-FS, BAT54-FS, and BAT55-FS series are engineered 5-tier ultra-low temperature (ULT) freezer storage racks designed for systematic, high-density cryogenic sample management in –80 °C to –150 °C environments. These racks integrate structural integrity with ergonomic workflow optimization—supporting standardized 133×133×54 mm cryoboxes (81- or 100-well format) while maintaining mechanical stability under prolonged thermal cycling. Unlike generic shelving solutions, each tier operates as an independent, full-extension drawer with integrated box retention features, enabling single-box retrieval without disturbing adjacent layers or requiring rack repositioning. The architecture conforms to ISO 15190:2020 requirements for laboratory biosafety infrastructure and supports traceability-aligned sample handling protocols essential for biobanking, clinical trial specimen archives, and GLP-compliant preclinical studies.
Key Features
- Structural grade stainless steel construction (0.6–1.0 mm AISI 304-equivalent), cold-formed and panel-stamped for dimensional stability at cryogenic temperatures
- Resistance spot-welded frame joints—validated for zero delamination or fracture after >10,000 thermal cycles between –86 °C and ambient
- Full-extension, low-friction drawer mechanism with reinforced front rails and positive-stop engagement
- Dedicated cryobox retention system: fixed-height internal baffles prevent lateral displacement; front-access cutouts allow direct vertical extraction of individual boxes
- Integrated label slot on each drawer face—compatible with standard 38×12 mm cryolabels and barcode sleeves for LIMS integration
- Modular column configuration (3-, 4-, or 5-column variants) optimized for footprint compatibility across major ULT platforms including Thermo Fisher TSX, Eppendorf CryoCube, Haier DW-86L, Meilin DW-86L, and DoLing ULT series
- Custom dimensioning available for non-standard cryobox formats (e.g., 96-well PCR tube racks, custom-sized vial trays); engineering drawings required prior to production
Sample Compatibility & Compliance
These racks accommodate industry-standard external dimensions for 81-well paper cryoboxes (133×133×54 mm) and 100-well polypropylene cryoboxes of identical footprint. Internal drawer clearance exceeds IEC 61000-4-2 electrostatic discharge (ESD) safety margins for cryogenic lab environments. All materials comply with USP extractables profile for low-temperature polymer contact surfaces and meet RoHS Directive 2011/65/EU restrictions on hazardous substances. The design facilitates audit-ready documentation under ISO 20387:2018 (biobanking) and supports 21 CFR Part 11-compliant electronic record workflows when paired with compatible LIMS barcode scanning systems.
Software & Data Management
While hardware-native, the rack system is fully interoperable with enterprise sample tracking platforms including LabVantage, Quartzy, and OpenSpecimen. Each drawer’s label slot enables consistent placement of scannable 2D DataMatrix codes adhering to AIM DPM-128 standards. When deployed in validated biorepository settings, the physical layout supports automated inventory reconciliation via robotic ULT freezer handlers (e.g., Hamilton STARlet cryo-modules) through standardized coordinate mapping (X/Y/Z grid referencing relative to freezer chamber origin).
Applications
- Long-term archival of primary human tissues, PBMCs, and stem cell lines in academic biobanks
- QC/QA sample retention for pharmaceutical stability studies conducted under ICH Q5C guidelines
- High-throughput screening libraries stored at –80 °C in drug discovery laboratories
- Viral vector and mRNA-LNP stock management in GMP-grade cell and gene therapy facilities
- Field-collected epidemiological specimens maintained under WHO-recommended cold chain integrity protocols
- Food safety reference strain repositories requiring ISO/IEC 17025-accredited storage conditions
FAQ
Are these racks compatible with non-Boante ULT freezers?
Yes—they are mechanically dimensioned to interface with standard interior rail systems used by Thermo Fisher, Eppendorf, Haier, Meilin, DoLing, Midea, Aucma, Eppendorf, and PHC Europe models.
Can I use plastic cryoboxes with different dimensions?
Standard configurations support only 133×133×54 mm footprint boxes. Non-standard sizes require custom engineering review and tooling adjustment.
What is the maximum load capacity per drawer?
Each drawer is rated for 15 kg static load at –86 °C, verified per ASTM F2697-21 accelerated life testing protocol.
Is installation hardware included?
No mounting brackets or fasteners are supplied—the racks are freestanding and rely on gravity-based stabilization within ULT freezer compartments.
Does the warranty cover damage from improper handling?
The 12-month limited warranty covers material and workmanship defects only; misuse, thermal shock due to rapid door cycling, or unauthorized modification voids coverage.
